Description

{Oyster larva's seed collecting board}

The present invention relates to an oyster larva grafted plate for a tidal flat ovine-type netting stand, which is mounted on an oyster-ovale net support and is capable of cultivating larvae spawned from bovine oysters cultivated in a positive net,

Oyster is a generic name of Filibranchia oyster and Bivalvia. It is a native species of ovum, usually called oyster, although there are oysters, gulls, barbets, wools, and peaches in Korea. . The oyster is a hermaphroditic body, but at the reproductive stage, it is an alternate hermaphrodite with a distinct male and female body and then a strong magnetism. The spawning temperature is 22 ℃ to 25 ℃ and the hatching larvae become valerian larvae I live a rich life, and after about 20 days, I go into attachment life.

The oyster shell grows about 7cm in length, about 60g in weight, about 10g in 2 years, 140g in 1 year, but grows slowly afterwards. Depending on the species, the place of oyster is somewhat different, and the oyster is relatively low in concentration of 11 ~ 32% It attaches to the rocks in the intertidal zone, and the burrows are attached to the rocks of the inner sea of 26-34% salinity.

These oysters are not only excellent in taste and flavor but also have a lot of essential amino acids among proteins and are called 'sea milk'. It is rich in calcium and vitamins A, B and C, Eating can prevent various diseases such as hypertension, stroke, arteriosclerosis, liver disease, cancer, etc.

These high-quality nutrients have been used worldwide to prevent the formation of oysters (Crassostrea gigas), Ostrea ariakensis, C.virginica, C.angulate, Saxostrea commercialiis, Bombay oyster .cucullata, O. edulis, and O. lurida.

Typical oyster cultivation is through seeding, rooting, harvesting. 'Harvest' is the process of artificially managing and cultivating the cultivation process by limiting the radius of life of the warts, and 'harvesting' Is the process of collecting or sampling.

The oyster culture of our country has a form of hanging down from the old days by the waves from the inside and the form of hanging down by the raising ceremony, the raft ceremony, the simple ceremony ceremony and the rope ceremony. In some cases, they are housed in floors or churns and underwater.

If you look at each of them briefly, the catamaran is put on a raft, which is a raft, and hangs on the bottom. This method is rarely used at present due to a large facility cost and inconvenience in handling. On the other hand, the rope type floats on the sea surface with a rope, is fixed with an anchor, and then hangs on the rope by hanging the lower part of the water. The above method is relatively large in the positive water area, Method. A simple method is to hang two rows of horses from the vicinity of the liver line to a depth of several meters and then to hang the bottom of the bamboo which is woven in the lengthwise and crosswise direction and the method of barking is to hang twigs between the bamboo and the crossing And the dialysis ceremony is to cultivate by putting stone on the exposed floor between high tide and low tide. However, it is difficult to efficiently maintain the spatula and to perform the work as the entire process of the work depends on the workforce. In addition, there is a great disadvantage in that the amount of harvest is reduced due to the occurrence of spoilage or natural loss of success or failure due to the flow of seawater.

In order to solve these problems, it is necessary to provide a stallion that can sculpt the oyster larvae, and a bennet netting that can cultivate the oysters and fortifications, The purpose of this study is to provide a grazing board which is installed in a tidal flat ovine netting installation where oyster larvae can be effectively harvested and cultivated even in a place where oyster farming infrastructure such as tidal flats environment is weak.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the tidal flats of the present invention will be described in detail with reference to specific configurations and attached drawings.

The oyster spawns in summer when the water temperature is over 20 ℃, and it is the most powerful when it is around 25 ℃. One mother gives birth to tens of millions of eggs. During a few metamorphoses over a period of two to three weeks, it enters a stable life and its size is about 0.3mm in diameter. Fixed depth is about 6m from the surface of water and sticks most 2m. Seedling for cultivation seeds oysters and scallops on a wire and hangs them in a shallow place.

After the seedling is over, it grows to a certain extent, then it is transported to the aquaculture facility, and after 2 to 3 months after the seedling, it is moved to a higher place and exposed for 4 to 5 hours to suppress the growth, It grows to about 15mm until about April, but after that it grows fast and is resistant to environmental changes.

FIG. 1 is a perspective view of a tidal flat omnitropic net installation stand capable of installing the jutting plate of the present invention. The tidal flat omnidirectional net mounting base includes at least one supporting member 54 formed by connecting one or more vertical members 52 connected vertically through a horizontal member 51 and a connecting hole 53. On the upper part of the support 54 is formed at least one positive net rest 55 on which an oyster-positive net can be placed. Between the support 54 and the support, At least one mounting member 57 capable of mounting the horizontal member 51 is formed in a vertical connection with the horizontal member 51 via a connecting hole 53. [

The vertical member 52 may be provided with a pedestal 56 connected to the vertical member 52 via a connecting port 53. The pedestal 56 may be adjusted to be positioned on the surface of the tidal flat so that the vertical member 52 It functions to prevent sinking to the tidal flat due to its weight.

In other words, the above-mentioned tidal flat ovine netting installation unit can be formed by combining oysters and oyster pots capable of harvesting oyster larvae, and a bennet netting unit capable of cultivating oysters, It is a structure that is capable of effectively harvesting and nesting oyster larvae in a place where the foundation is weak.

Figure 2 shows a perspective view of a grape leaflet capable of harvesting oyster larvae. The patchwork panel installed on the tidal flat omnidirectional net mounting base is composed of a mesh net having a polygonal outer frame (61) and small enough to attach oyster larvae on its inner side, and has a " Shaped protrusion 64 is formed so that the protruded protrusion can be pushed into the recessed groove of the embossed plate mounting member and fixed.

The mitral plate mounting portion of the positive net mounting portion coupled with the protrusions formed on the top and bottom surfaces of the tabletop has one side of a "c" shape so that the convex protrusions of the tabletop are inserted into the "c" And is detachably formed while being slid. In this case, the "C" -shaped grooves of the embossing plate mounting member are provided at the upper and lower ends of the mounting member, respectively, so that the lower portion of the embossing plate is first fitted to the embossing plate mounting member, As shown in Fig.

On the other hand, the larvae of oysters emitted from seawater in the tidal flat ovine netting installation are attached to the netting of the netting of the inner part of the jade box frame after being suspended for a certain period. However, since the diameter of the netting of the netting is small due to the maturing of the netting, the netted netting grows larger than the mesh, so that the sea water is not smoothly flowed, There is a problem in that the effect of the installation of the tidal flat omnidirectional net is reduced.

Figures 3 and 4 show a perspective view of an evacuation plate capable of embodying the improved oyster larvae of the present invention. The modified grating plate has a polygonal outer frame 61, a mesh network of small enough to attach oyster larvae to its inner side, and a "A" shaped protrusion protruding outward from the outer frame at the upper and lower corners 64 are formed and the protruded protrusions are formed so as to be pushed into the concave grooves of the embossed plate mounting member to be fixed thereto are similar to the embossing plate provided on the benign net mounting stand developed by the present inventors.

However, as shown in FIGS. 3 and 4, the polygonal outer frame 61 includes an inner frame 62 in which one or more support frames are installed in a stitching space 63 formed in a predetermined area, and the stitching space 63 Is provided with crossing connection lines 66 for connection to the outer frame from the one side outer frame and one or more drainage holes 65 are formed at the intersection of the support frames formed in the mining space, To facilitate the distribution of currents.

The drainage hole 65 is connected to the inner frame 62 to form a polygonal shape, thereby preventing the deformation of the seedling due to the seawater flow and maintaining the solidity. For the slaughtering, a description of a certain diameter is formed by a mesh of a certain size crossing the upper, lower, left, and right sides across the slaughtering portion of the frame.

It can be installed according to the speed of the ground or seawater circulation speed where the tidal flat omnivorous fishing net installation base is installed by varying the location of the point of intersection of the description with the inside of the frame, the number of crossing net, the size of mesh, To provide a modified deck plate. The material of the polygonal outer frame is usually made of synthetic resin. In order to increase the weight, iron or stainless steel can be used. Stainless steel can be used for the exterior and synthetic resin for the interior. By providing the drainage through holes 65 differently from the number and arrangement of the drainage holes 65 formed in the inner frame 62, the efficiency of the circulation of seawater is increased and the resistance of the seawater due to the circulation of the seawater is reduced .

Figure 5 shows a modified embodiment of a grape leaf which is capable of grinding oyster larvae of the present invention. The modified deck plate comprises a polygonal outer frame (61) formed so as to be installed between a support and a support of a tidal flat omnidirectional net installation stand; The upper side or lower side edge of the outer frame is provided with a projection 64 protruding outwardly from the outer frame so as to be able to be mounted on the support frame; A stitching space (63) formed inside the outer frame with a constant area; And an inner frame 62 in which at least one support frame is installed at a crossing space in the stitching space. At least one knot engraving work 66 made of natural fibers or synthetic fibers is connected to the support frame by one or more knots. That is, in the support frame formed in the stitching space 63, at least one string is connected to one or more knotting rods or a stringing work 66 made of natural fibers or synthetic fibers.

Fig. 6 shows an enlarged knot of an embodiment of a modified jute board. 5, the amount of spots attached to the positive net can be reduced while the mesh of the net is increased. As described above, since the inner frame 62 may have a small amount of embroidery, the embroidery thread made of a net may be reduced in size. Therefore, the support frame formed in the embroidery space 63 is knotted By using the connected work, we can grasp oyster larvae. According to this configuration, the passage for seawater circulation of the tabletop can be secured and the flow of the currents can be smoothly performed, and the synthetic fiber or natural fiber can be easily adjusted and knotted by binding the support frame with a knot.

By using the inventive sheathing board, it is possible to improve the problem of the seawater flow caused by the existing sheathing boards mounted on the marsh bullfighting net installation stand, and it is possible to stably mount the benches in the weak support base It can increase the productivity of the oyster farming industry because it can produce a large amount of spatula without obstructing the distribution of the ocean currents. It will increase the income of the fishermen by improving the international competitiveness of the aquaculture technology, There is a potential for industrial applicability that can contribute to this.
